<p>短信登录是使用手机号和验证码进行登录。</p>
<h2 id="短信平台">短信平台</h2>
<p>很多云平台，比如阿里云，腾讯云，七牛云等云厂商，向程序开发者提供了短信验证码套餐服务。借助云平台的短信服务，程序开发者可以非常简单方便的将短信服务集成到自己的程序中。</p>
<p>在本节课中，我们以接入和集成阿里云的短信服务sdk为例进行讲解。</p>
<h2 id="阿里云短信服务集成">阿里云短信服务集成</h2>
<p>在本次课程中，我们集成的短信服务以阿里云平台为例。在实际的开发和选择中，也可以是其他平台，原理类似。</p>
<h3 id="登录阿里云">登录阿里云</h3>
<p>登录阿里云：https://www.aliyun.com/</p>
<p>选择短信服务模块：https://www.aliyun.com/product/sms</p>
<p>注明：云平台的短信服务是收费的，有不同类别的套餐。开发者可以按照自己的需求进行选择。如下图：</p>

</code></pre></div><h5 id="2创建签名和短信模板">2、创建签名和短信模板</h5>
<p>在使用go sdk集成短息服务之前，需要首先创建短信签名和短信模板。</p>
<p>**签名：**短信签名是短信服务提供的一种快捷、方便的个性化签名方式。当发送短信时，短信平台会根据设置，在短信内容里附加个性签名，再发送给指定手机号码。比如，下图红框中的&quot;招商银行”就是这条短信的签名，用以标识发送者的类别等内容。</p>
<p>在阿里云后台的短信服务控制面板的左侧功能栏中，选择国内消息，如下图所示，然后选择签名管理的TAB，然后选择添加签名，可以创建新的短信签名。如下图:</p>

        </a>
    </p>
<p>**短信模板：**短信模版，即具体发送的短信内容。短信模版可以支持验证码、短信通知、推广短信三种模式。验证码和短信通知，通过变量替换实现个性短信定制。
与创建签名同理，可以在模板管理TAB中，选择添加模板，用来创建新的短信模板。创建完成后，会进行审核。</p>
<p>创建成功后的短信模板的模版CODE需要记住，后续会使用到。</p>
<h5 id="3创建accesskey和accesskeysercet">3、创建AccessKey和AccessKeySercet</h5>
<p>在短信服务管理平台的概览界面，可以选择AccessKey按钮进行创建集成短信服务所需要的AccessKey和AccessKeySecret。</p>

<p>在实际的开发中，程序功能往往是分层来进行开发的，controller层只负责控制和处理接口请求的逻辑，具体的功能调用，往往由另外称为service层的功能服务层来进行实现。</p>
<h4 id="创建service层">创建service层</h4>
<p>在service层中，依然按照模块化开发的理念，将用户模块的服务统一由UserService进行提供。因此，创建MemberService,并提供SendCode方法。</p>
